Area of Science:

  • Veterinary Medicine
  • Equine Surgery
  • Histology

Background:

  • Sternal bone biopsy is valuable for diagnosing equine conditions.
  • A minimally invasive technique for standing horses is needed.

Purpose of the Study:

  • To develop and evaluate a technique for sternal bone biopsy in standing horses.

Main Methods:

  • Five adult horses underwent biopsy using an electric drill after sedation and local anesthesia.
  • The sternal biopsy site was identified ultrasonographically.
  • Specimens were processed for histological and histomorphometric evaluation.

Main Results:

  • The 4th or 5th sternebra was the optimal biopsy site.
  • The procedure was easily performed, well-tolerated, and yielded adequate samples.
